Original application filed March 9, 1925, Serial No. 14,013. Divided and this application led Hay 6',

192s. serial No. 107,048.

This invention relates to printing Vpresses and is more particularly concerned with presses of the bed and cylinder type, wherein the bed reciprocates. The general object is to vprovide a. very simple and efiicicnt mechanism for maintaining proper lubricant between the` traveling bed and its support- More specifically, the invention comprises a reciprocable roller frame, mounted between the stationary supportl and the` traveling bed, and' an oil carrier secured to the roller trame and adapted toidip in oil on each reciprocation and deliver it to the trackway on which the roller fra-me travels. The invention is l5 hereinafter more fully described., in connection with a preferred embodiment illustrated in the drawings, and the essential characteristics are summarized in the claims.

In the drawings, Fig. 1 is a vertical longitudinal section through a bed and cylinder printing press embodying my invention, the lane of the sect-ion being indicated on the line 1 1 in Fig. 3; Fig. 2 is a transverse vertical section on the line 2 2 of Figjl Fig. 3 is a plan of the printing press, particularly broken away; Fig. 4 is a perspective of a portion of the roller frame and the oil carriers carried thereby; Fig. 5 is a detail in vertical section, of one of the oil carriers and its oiling trough. v,

I will first describe briefly the printing press shown, and then, in detail, the oiling system and the spacing means for the rollers constituting this invention.

The stationary frame of the machine may be of any suitable form. It is shown as comprising a horizontal bed plate 10. depressed between side walls 11, which merge into suitable supporting legs 12. The side walls have external iianges 14 on which are mounted Standards 15, carrying the shaft 20 of the rotary platen 21, Aprovided with paper. gripl pers 22. n

Formed on the upper surface of the stationary bed plate 10, are. trackways for the rollers of the roller frame. Four of such trackways, as shown are designated 17. Resting on these trackways are the rollers 30 of the roller frame about to be described and 0 resting on these rollers. is a reciprocatory bed 40. carryingl the type form.

The present applicati onis a division of my 1o-pending application No.14.013,filedMa'rch 9th, ,lgwhicli has resulted in PatentNo.

1,638,544, issued August 9, 1927. I will first vdescribe my novel means for positioning the rollers of the roller frame. The four rows of rollers shown are grouped in two sets, each set being mounted on a positioning member comprising a longitudinal channel-shaped spacing plate 32 having down turned flanges 33, and a series of rods 35, mounted on these flanges. The rollers 30, are journalled on the projecting ends of these rods, suitable Washers Vand pins 37 maintaining the rollers in place. The .stationary tracks 17 are preferablyhardcned horizontal strips and the flanges 38 of the spacing' members extending lower than the rollers along the inner side of these strips and thus prevent lateral displacement of the roller frame. y v The reciprocatory type bed 40 has downwardly extending webs 41 on the underside of which are hardened strips 42, which rest on the rollers. This traveling bed is guided by the lining strips 44 on the inner sides of the frame sides 11.- This bed carries a suitable chase 45 between bearing stri s 46which coact with the platen roller. Tile bed may have the rack 47 adapted to coact with a gear 25 on the platen roller. l Any suitable means may be employed .to reciprocate the bed 40. As shown, it 1s pmvided with a downwardly extending vertical guideway 50, rigidly secured to the underside of the bed. In this guideway, is a sliding block 51, which is secured to one length of an endless chain 52. mounted on sprockets 53 and 54, carried by thestationary frame. ne of these sprockets is driven to operate the chain continuously. I have shown a driving belt 60 operating on a pulley 61 which is keyed lto the shaft of sprocket 53. Another belt 64, running from a pulley on this same shaft to a pulley 27 operates the platen roller 21.

It will be seen from the construction de.

manner of the Scotch yoke. At the same time, .the platen is rotated by itsbelt-v andmay be maintained in proper registration with the tvp'e form by the rack and gear mentioned.

Suitable eccentric mechanism, indicated 8.4528

but not shown in detail, mayrise platen Cil Y strate clear of the rack il?, so that it rotates idly on one stroke of the bed.

The above described driving` mechanism, which is substantially copiedV roin my copending application No. 602,161 liled November 30th, 1,922, is shown simply as illustrative ot' any means for reciprocating the bed. l/ilhen the bed is thus reciproca-ted, it rolls on the rollers 30, `and these rollers roll on the tracks 17 of the stationary hed, so that the whole roller trame has a travel lirst in one direction and then in the other equal to half of the stroke of the type bed.. fr feat-ure ot theV presentinvention is the. means for inaintaining the tracks for these rolle-rs constantly lubricated. This will now be specilically described.

The stationary bed l0 is extended at the end ot' the machine and formed into two horizontal troughs T0, Figs. l, 3 and l5. These troughs are adapted to contain lubricating oil indicated by 71, Fig. 5. (ln the endmost rods 35 of the roller spacers 32, are pivotally mounted sets ot links 75 each adjacent pair ot which carry a ioller 75.

VAt the end ot the stroke, the rollers 76 occu'py the pockets 70, as shown in Fig. 5, and are thus immersed in the oil. Then, the

roller frame moves, such rollers ride up on the frame incline 78, Fig. 5, and thereafter travel along the trackways l?. They tlius distribute oil to these trackways, which is taken up by the rollers 30 and by them distributed to the undersidcs of the bars of the guide tracks l2 on the undersurface of the reciprocatingbed.

It will be seen from Fig. 2 that the bed carries ribs 18 on its upper surface located on `opposite sides of the trackwaysl?, parallel therewith and some distance therefrom, thus providing oil channels into which .the surplus oil may pass from'the tracks 17 and eventually reach the pockets 70.

It will be seen that the oiling device is extremel simple. vExperience has demonel7 that it is very eiective in maintaining the 'trackways properly lubricated. The amount of oil in the pockets 7() may be readily inspected, and thus replenished asnecessary. Having thus described my invention, I claim 1. In a printing press, the combination of a Vsubstantially horizontal trackway, a reciproeating member mounted thereon, an oil carriercarried by the reciprocating member, an

oil receptacle into which the oil carrier Vdips at each cycle of operation of the reciprocating' member, said oil carrier being adapted toconvey'oil to the tr'ackway supporting said reciprocating member.
